Carburetor Question - Is this a good call?

Thanks all - i was JUST about to head to Lowe's and decided not to because i didnt think they would have any SAE 8-ish bolts at all... but ya - i'll be searching these 3 asap.
Don't need Grade 8 bolts for this issue...just get whatever Allen heads they have...you aren't torquing them down very tight anyway...it's just an aluminum plate.
